The only reason to derive from 'object' is if there is some sort of
weird side effect of using new style classes. I _have_ run into some
interesting scenarios when creating com objects in python using the
win32com module. Other than that, I always use new style classes
(derived from object).

Here are some articles that point out the distinctions between old and
new style classes: http://python.org/doc/newstyle/
